Dr. Kaelee Brockway, PT, DPT, EdD, dives into the power of high-intensity interval training (HIIT) and how it can transform care for patients with complex chronic conditions like heart failure, COPD, diabetes, renal disease, and vascular insufficiency. She explains that HIIT goes far beyond improving mobility—it sparks changes at the cellular level, promotes left ventricular remodeling, and helps regulate blood glucose. Kaelee stresses the importance of building multi-system stability first, monitoring vitals throughout, and tailoring each program to the individual. She brings her points to life with real-world stories, including patients who came off supplemental oxygen and even cut down dialysis time. Her big takeaway: in home health, we often underdose exercise. Pushing patients a little harder not only drives better outcomes, it boosts engagement—for both patients and clinicians.
